Pandora Could Be Devastated by a Free Spotify

Spotify's upcoming free option for its mobile listeners will be a major competitive threat to Pandora, even moreso than Apple's iTunes Radio. As competition in the space intensifies, drawing in heavyweights like Googe, Pandora's future continues to look bleak.

I am utterly baffled by Pandora's (NYSE:P) steady share-price appreciation. It's an unprofitable company with an unproven business model whose major competitors include Apple(NASDAQ:AAPL) and Google(NASDAQ:GOOGL), two of the largest and most powerful tech companies in the world, and who incidentally happen to own the platforms Pandora depends on to reach the overwhelming majority of its listeners.

But while I think Apple and Google's expansion into the market could ultimately prove overwhelming for Pandora in the long run, Spotify's new initiative has the potential to be even more detrimental.

Spotify goesfreePandora's management would tell you Spotify isn't a competitor in the true sense of the word. Spotify offers on-demand music; if you want to listen to a particular song or a particular artist, Spotify will let you do that. But sometimes you don't want to -- sometimes you want to kick back and be served up a steady stream of songs. That's where Pandora comes in.

It's possible that Spotify and Pandora are serving two distinct markets. In reality, if you look at the listener metrics, I think it's obvious that demand for both services is highly overlapping -- Pandora simply benefits from an uneven playing field.

There's an important distinction here: desktop and mobile. If you're on a traditional PC, both Spotify and Pandora are free to use. But for most people, listening to music is better on the go, such as in the car, at the gym, or walking around town -- times when you're far away from your computer. In those instances, listeners turn to their smartphone or tablet -- where Pandora's massive advantage comes into play.

On mobile devices, Pandora's service is still free. Spotify's, however, is not -- if you aren't willing to pay a monthly fee, you're out of luck. But that is set to change next week, when Spotify is reportedly going to announce its own free option -- going forward, listeners will be able to access Spotify's service on their mobile device without paying. Over time, Spotify's free option should cannibalize many of Pandora's listeners.

Consider listener metrics: Spotify has about 24 million active listeners, but only 6 million of them are willing to pay for mobile access -- about 18 million stick with the free desktop option. In contrast, Pandora has many times more active listeners -- about 72.4 million -- but around 80% of them listen from a mobile device. That means that Pandora, despite having so many more total listeners, actually has fewer desktop listeners than Spotify.

In essence, other things being equal, listeners seem to prefer Spotify's service over Pandora's when both are free. Now, there may be other factors that could have an effect -- perhaps the desktop setup is better for selecting individual songs than a mobile interface -- but I think it's likely that Spotify's free option could rob Pandora of millions of listeners.

Apple and Google moving inBut I don't think Spotify's new initiative is, by itself, the single strike against Pandora. Rather, the entire space is seeing rapid advancement, and Pandora is facing a new competitor seemingly every quarter. Pandora shareholders cheered on November's active listener numbers: after a slight drop in October, Pandora posted a gain in November, suggesting the competitive threat from Apple's iTunes Radio was at most minor.

But Apple's iTunes Radio has only been around for just longer than two months, and music lies at the core of Apple's iOS ecosystem. Even if listeners prefer Pandora over Apple's iTunes radio right now, it's only logical to expect Apple to improve on its offerings. Moreover, as Apple moves into the living room and into the automobile, Apple as a competitor isn't going away anytime soon.

Owners of devices powered by Google's Android operating system can't access Apple's iTunes Radio even if they wanted to, giving Pandora an obvious advantage on Google's platform. But again, Google's option is new -- just about six months old -- and its evolution is ongoing. Google Music was only added to Apple's app store last month, and like Apple, Google has only begun to expand its Android ecosystem to the living room and into the automobile.

These long-term "what-if" scenarios may seem underwhelming -- the possibility of Google and Apple definitively crushing Pandora in the long-run is conjecture at this point. But Pandora isn't some established company -- it's a speculative investment at best, and it can't even reach the majority of its listeners without Apple and Google's help.

Pandora has been a great stock to own in 2013I've been bearish on Pandora for months, and for months I've been completely wrong. In just the past six months alone, Pandora shares have almost doubled. Year to date, they're up more than 200%.

Ultimately, however, I remain as negative on Pandora as ever before. This is an unprofitable company with a terrible story, beset by challengers on every side. In the long run, Apple and Google could weigh heavily on Pandora -- their platform ownership gives them the upper hand -- but in the near term, competition from a free Spotify could be even more devastating. Pandora shares might continue to run, but this is one stock I think long-term investors should avoid.
